(OP)
Does anyone know where I can find a fatigue (SN) curve for 2219 T852, at a Kt=1?

RE: fatigue curve 2219 T852 Kt=1
The typical curve has the following values:
Life Stress (ksi)
10^4 46
10^5 34
10^6 26
10^7 20
10^8 16.5
5x10^8 15
This would be for rotary bending load, R=-1 at room temp.
Also look for Rateick, et.al., Relationship of microstructure to fatigue strength loss in anodised aluminum-copper alloys,
Materials Science and Technology, Volume 21 (2005), No. 10, pp. 1227-1235

RE: fatigue curve 2219 T852 Kt=1
yes. They only contain Kt=2 and up. While using that would be conservative, it is double dipping because we already use peak stress from FEA. Thanks though.
